Application February-i5, 195'35-S`eri'al No: 335201)' 7 Claims. (ci.itz-17) This invention relates tormean's for' slitting portions ofk shoeuppers andl is herein illustrated 'as embodied in1 a device for slittingthe' margin of a platform wrapper in order to facilitate the subsequentdisposition of the Wrapper. 'It is to be understood, however', thatin0vari:- ous novel aspects the invention is not limited tothe illus'-trative embodiment thereof.

It' is' an object of the present invention' to' providejal simple andconvenientlyl operatedi device` which may bei mounted adjacent to anupper shaping n'iachine and-manually operated? by the' operator of" the'machineY to' slitthe freernargint of the platform Wrapper in order tofacilitate' theJ shapingl operation;

With the above object in view the invention in one aspect thereofcomprises a stationary cutter having. a

fixedl cutting station, a' shoe"carrier"constructedl` and ar- I rangedto supportthe forepart of a' shoe in' Yupright'gposition, and meansherein illustrated as a bench fixture mounting the carrier for movement'lengthwiseof a shoe thereon relatively to the cutter. In the illustratedorganization the iixture provides a, mounting for` both the cutter andthe carrier. The carrier is preferably slid'ablyY mounted on the ixturefor a' rri'o'velnent'A of: translation relatively to the cutter.carrier, a detent mounted in the' xtureJ holds the carrier against'movement' relatively t'o th'e cutt'er`V so that the carrier provides ashieldwhic'h prevents accidental contact of the angers cf the operatorwith the' cutter, the

When' there is no' shoe` on the'- detent being characterized by anextension constructed',

and arranged tobe engaged bya shoe as it is mounted in the carrierthereby to displace the detent from its operative position in order:topermit movement of the carrier relatively to the fixture. In the:illustrated organization the' carrier is so constructedf and. arrangedthat one edge thereof is engaged by the innen surface of" the free.margin of the platform: wrapper of ai shoe positioned on the carrier andthus the carrier isfadvance'd with the shoe by manual movement. of. theshoe toward the operator. Such a movementfofthe shoe transfersl the shoeina path such thata portion of the margini oi the plat-form wrapperpasses through theA` station occupied I by the cutting edge of thecutter and is slit thereby.

In the illustrated organization a plurality of cutting blades areattached to the iixture and have their cutting edges disposed in planesextending heightwise of a shoe on the carrier so that a plurality ofslits are cut substantially concomitantly in the margin of the platformwrapper during the movement of the shoe.

The invention will now be described with reference to the accompanyingdrawings and pointed out in the appended claims.

For 'mountingthe illustrated; mechanism an inverted Uishaped'braclet10"is securedto the topofalbe'nch'lz By' bolts I4; andv` arranged to"extendv` verticallyv upwardly." therefrom; the 'front of the ben'ch12`1being to the. left as" seen in Fig. l. A fixture herein illustratediasapla'te 16" isfrigidly'secured'by'headedv screws 18 to the horizontalvportion of' the'Y bracket 10' andi isr arranged toA extencr to' theright fro'm the' bracket as seen`in Figi' l;

At itsL riglite'nd portion, as seen in Eig. 3", the' fixture 16isrecesscd at* 1`9lto provide" therein a p1ne verticali surface"coincidental with thelon'gitudinaf center li`ne of thetixture. A centralc'utting'blzrde` 2 0 is'located against. said surface and is secured4thereto by a headedl clampingk screw 22 which;` as shownin Fig., 2iextends through an open-ended' slot` 2'4 in the'left' endportion of"thecutting' blade. The square end portion of the cutting' blade` is'seatedl against the` base' of a narrow groove formed in the fixture 16;in orderto cause'the blade' to berilgidly retained in thev fixture andto` he securely' held` against* angular' movement; To provide f'or themounting'oftw'o cutting blades zthe'iixture isre'cessed at oppositesides thereof toA provide planeY verticali surfaces parallel"Y tothe'longitudinal center line of the' fixture forthe mountingV` of twocutting4 blades" 26. The'V blades 26j are seated in narrow grooves` inthe fixtureA sirnilar'to the groove providedV for' the* blade 20% andare secured againsttheverti'- cal" surfacesy above referred to byclamping screws 28 ex'- tendi'ngl through open-endedAY slots (notshown)v in the cutting blades; As'shown in Fig: 3', the centralj cuttingblade 20!` is offset to the right from the' blades 2'6 which arelo'catedjdirectly opposite each otherso that the" three blades willoperate substantially.4 concomitantly on the margin of aY platformlWrapper' ats one end: of* a shoe.

For supporting' theV forepart, of a shoe in upright posti tion, as`shownl in Figs: l and' 2;, a carrier herein illust'rated as a plate 30,is slidably mounted on the fixture' 126" and" its' oppositemarginalportions ('Fig'. 4)," are` bent to formwhannel sections 3"'2vwhich embracen the' reduced! marginal portions 34;V atV oppositesides ofthe fixture 162 These marginal portions serve" to guide' thecarrierplate tension spring 36 mounted in a cylindrical groove 38Lformed in the fixture 16 and extending from the left end of the plate asseen in Fig. 3 to its central portion along the longitudinal center lineof the fixture. As shown in Fig. 2, the left end of the spring 36 isanchored to a pin 40 mounted in and projecting downwardly from thecarrier plate 30, and `the right end of the spring is anchored to thereduced upper end portion of a headed screw 42 mounted in the bottom ofthe fixture 16 and projecting upwardly through the groove 38. The spring36 normally holds the carrier plate 30 at the limit of its movement tothe right, as shown in Fig. 3, in a position determined by theengagement of the head 44 of a detent in the circular portion of akeyhole slot 46 formed in the carrier plate 30 and extendinglongitudinally thereof midway between its opposite side portions.Referring to Fig. 2, the head 44 of the detent is cylindrical v Y 3 inshape and has an annular ange 48 at its base the edge face of which isarranged for sliding engagement with the cylindrical surface of avertical bore 50 in an externally threaded member 52 seated in a tappedbore in the iixture 16. The detent is urged upwardly by a spring 54surrounding a stem 56 extending downwardly from the head of the detentthrough a bore in the base 58 of the member 52, thespring being confinedbetween the base 58 and the head of the detent. The head of the detentis moved downwardly out of the circular portion of the keyhole slot bythe engagement of the sole of a shoe with the upper extremity of a stem60 extending upwardly from the head 44 of the detent, said stem beingslightly less in diameter than the width of the narrow portion of thekeyhole slot. l

In the operation of the illustrated cutting means the forepart of a shoeis arranged in upright position and mounted on the carrier plate 30', asshown in Fig. l. The illustrated shoe comprises an upper 62 stitched toa. sock lining 64 (Fig. 2) to which there is also stitched a wrapper 66covering the edge face of a platform 68 cement attached to the socklining. A last 70 has been inserted into the shoe in accordance with theusual practice in the manufacture of slip lasted footwear. The shoe isso located on the carrier plate 30 that the innersurface of thedownwardly projecting margin of the plat form wrapper 66 at one end ofthe shoe is arranged in contiguous relation to the edge portion 35 (Fig.3) of the carrier plate, said edge portion having a contour generallysimilar to the peripheral contour of an end portion of the platform 68.In mounting the shoe on the carrier the bottom surface of the platform68 engages the upper end portion of the stem 60 and forces the detentdownwardly against the pressure of the spring 54 displacing the head 44of the detent from the circular portion of the keyhole slot 46 andleaving the carrier free to move to the left as seen in Figs. 1 to 3.After mounting the shoe on the carrier plate 30 the operator moves theshoe endwise, or to the left, as seen in Fig. l, the carrier platemoving with the shoe by reason of the engagement of the platform wrappertherewith. It will be seen that the movement of the shoe from itsposition in Fig. 1 into its position illustrated in Fig. 2, causes thecutters 20 and 26 to cut open-ended slits in the downwardly projectingmargin of the platform wrapper. After the movement of the shoe with thecarrier plate 30 has been terminated by the engagement of the small endofV the keyhole slot with the stem 60, the operator lifts the shoe fromthe carrier plate and the spring 36 returns the carrier plate to itsrest position illustrated in Fig. 3, whereupon the spring 54 moves thedetent upwardly into its locking position.
